AEROPLANE $T11Y AND TEE LIKE.

Application filed May 23,

T 0 all whom it 772 (511/ conccrn Be it known that I, HAROLD J. l-lonn, a citizen of the United States, residing at Trenton, county of Mercer, and State of New Jersey, have invented certain new and useful Improvements in Aeroplane Stays and the like, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to aeroplane stays and the like. i

In certain structures such, for example, as aeroplanes, it has been found difficult to effectively anchor the ends of the stay wires, especially those of the flattened or stream line type.

It is the especial object of the present invention to provide means for properly and efiectively anchoring the ends of such aero-. plane stays, but the invention is applicable also to anchoring or attaching metal wires or bands of other forms, and for other purposes.

The present invention embodies a species of an invention more generically claimed in an application #286,133, filed May 23, 1918.

The following specification describes and the accompanying drawings illustrate various embodiments of the invention, it being understood that changes may be made in the form, construction and arrangement of the parts without departing from the invention.

For purposes of illustration, stays of the flattened or stream wire type are shown, and these stays are crimped, as hereinafter described, adjacent the end to be anchored. In structures embodying the invention, the

1918. Serial No. 236,132.

crimped portion of the stay is embraced by a plurality of anchoring members corrugated to correspond to the conformation of the stay, and these members are fastened in this interlocked relation with the stay. Although capable of various constructions, in the form shown in Figs. 1 to 5, a stay 15, crimped adjacent its end, as hereinafter described, is embraced between two anchoring members 16 and 17. These members, on one side, are corrugated to embrace. the crimped stay in interlocking relation as clearly appears in Fig. 8. The outer surfaces of the anchoring members are rounded and somewhat flattened. To fasten these members in the in terlocking relation described, they are bound together by a relatively large number of turns of a flexible binder 18, such as small wire, cord or the like, the ends of the binder being suitably secured as by being turned under at the ends. To aid in preventing the fastening binder from slipping, the anchoring members are slightly dished to form shoulders, as at 19 and 20, which serve as stops to engage the binder. Vi ith such a construction, the stay is securely and firmly held in interlocking relation with the anchoring members which are fastened in place-so as to be substantially immovable.

Means is provided for connecting the anchored stay with a terminal which may be any portion of the aeroplane or other structure to which the stay is to be secured, and in structures embodying the invention to the best advantage, the anchoring members themselves are connected with the tern nal and the connection includes a universal joint. Although capable of various constructions, in the present embodiment the terminal which is, for example, a frame bar 21, is embraced by a forked lug 23 secured in place by a pivotal pin 22 on which the lug swings, this lug being formed on the end of a connecting stem 24 which is threaded through the collar 25 of a member having a swinging connection with the anchoring .iembers. Extending out from opposite sides of the collar 25 are curved wings 26 which are received in slots 27 formed in wing portions 28 bowed outwardly from the an choring members, as shown more clearly in 1. The slots 27 permit the winged member 25 carrying the connecting stem to swing loosely as if about a pivot, its movement being limited by the engagement of 25a straight line.

3 5 portion.

either wing 26 with the anchoring members. The plane in which the winged member swings is at right angle to the plane ot the forked lug 23 and consequently there 5 is a universal joint connection between the anchoring members and the terminal.

To adjust this connection, to take up slack orthe like. the connecting stem 24 is moved relatively to the collar 25, by means of its n threaded relation therewith, and a lock nut is provided to hold the parts in the desired position.

The invention includes provision for obtainingthe full strength of the wire and. for

15 distributing the strain on the crimps. This is accomplished by varying the degree of the crimps, and in structures embodying the invention to the best advantage, the crimps gradually increase in degree. As more 0 clearly appears in Fig. 3, the stay wire 15 is shown formed adjacent its end with a plurality of crimps, which, as-will be apparent, vary in degree. The first crimp 31 is relatively slight, its angle being not far from The next crimp 32 is slightly more pronounced, and this increase in degree is gradual until the final. crimp 33 at the end of the stay is fairly sharp. It will be understood that the precise number 30 of crimps is immaterial. lVith a construci0 crimped as before described, is embraced between anchoring members'O, 41 corrugated to correspond to the conformation of the crimped stay and fastened in place by flexible binder 18 in the same manner as before 4 5 described.

The invention includes means for interlocking the forward ends of the anchoring members, and in structures embodying the invention to the best advantage, the anchor- 5 ing members have intercrossing portions through which the stay passes. Although capable of various constructions, in the form shown one ofthe anchoring members, for example,theone designatedas 4:0, is formed at its forward end with an oblique inwardly extending tongue 42. As this tongue extends across the path of the stay, when the anchoring member is in position, it is formed with a suitable opening 44: for the passage of the stay. The other anchoring member 41 is provided at its forward end with a hook'shaped tongue 45 extending across the path of the stay, and provided I with an opening 46 for the passage of the stay. TlllS anchoring member all is also formed with a transverse slot 47, for the reception of the tongue 422 of the other anchoring member. YVhen the parts are in place the tongue 45 of the anchoring member ll hooks over the outer end of the anchoring member 40, the tongue 42 of the latter entering the transverse slot 47 and the stay passes through the openings in these intercrossing tongues to effectively in the crimped stay.

2. In securing means for aeroplane stays andthe like, a'substa-ntially rigid and nonflexible stay crimped 'adjacent its end, a plurality of anchoring members correspondingly formed to embrace the crimped portion, and a flexible binder for fastening said anchoring members in interlocking relation with the crimped stay.

3. In securing means for aeroplane stays and the like, a terminal, a stay formed adjacent its end with crimps of varying degree, a plurality of anchoring members corresponding-1y formed to embrace the crimped portion, a flexible binder for fastening said anchoring members in interlocking relation with the crimped stay, and means for connecting the anchored stay with said terminal.

4. In securing means for aeroplane stays and thelike, a terminaha stay formed adjacent its end with crimps, a plurality of anchoring members correspondingly formed to embrace the crimped portion, means for fastening said anchoring members in interlocking relation with the crimped stay, means for connecting said anchoring'members with said terminalincluding slotted wings associated with said anchoring members and a winged member mounted to swing in said slots.

5. In securing means for aeroplane stays and the like. a stay crimped adjacent its end, a plurality of anchoring members correspondingly formed to embrace the crimped portion and interlocked at their ends, and a flexible binder for fastening said anchoring members in interlocking relation with the crimped stay. V

In testimony whereof, I have hereunto set my hand.
